Today I am studying about waves. So, we learn the formula "speed = frequency * wavelength". There is a question come out in my book
If the frequency of water waves is decreased, what will happened to its speed?
So, this is what did,
- If speed = frequency * wavelength
- That means speed is directly proportional to frequency
- When frequency increases, speed increases and vice versa.
Eventually, I write the speed of the water waves will decrease. But the answer from the book is the speed of water waves will stay constant.
So, my question is why the speed of water waves will stay constant if the frequency of water waves is decreased?
